Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is a combination of a stove part or a grill part having a stove function or a grill function such as an electric stove or grill on the upper part of the appliance, and a microwave oven and a gas oven in the lower part of the appliance. The present invention relates to a heating cooker equipped with a composite cooker.

Structure of the conventional example and its problems As shown in Fig. 1, the conventional combination oven 11 has a stove part 3 equipped with an electric stove 2, a combination microwave oven and a gas oven in the lower part of the appliance. A cooling layer 26 is interposed to cut off mutual thermal interference with the composite cooking device section 5 provided with the cooking device 4, and a small dedicated fan 27 is attached to this cooling layer 26. Hot air within the cooling layer 26 was forcibly discharged. In this conventional configuration, in addition to providing the dedicated fan 27, measures against vibration or noise are also required, which complicates the configuration of the device and increases cost. In addition, warm air is discharged from the front of the device, making the user feel uncomfortable. Furthermore, an exhaust port 29 is provided on the top plate 7 of the electric stove 2, so that about 4 of the top plate spaces are taken up by the exhaust port 29, and therefore, the number of electric stoves 2 is 30.

Furthermore, the exhaust air from the combined cooking section fills the room through the exhaust port 29, causing dirt in the room, toxic exhaust residue such as carbon oxide, and unpleasant odors.

Purpose of invention The present invention aims to eliminate the above-mentioned conventional drawbacks.

Composition of the Invention The present invention provides a stove part located in the upper part of the appliance and having a stove function, a composite cooking part located in the lower part of the appliance and having a composite cooking device that combines a microwave oven and a gas oven, and the composite cooking device. There is a combination cooker equipped with a cooling fan for cooling the electrical control parts of the combination cooker, and an exhaust (

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. Also, are the numbers in Figure III the same for the same parts? View with donations.

In Figures 2 and 3, 1 indicates a heating cooker, with a stove 3 having a stove 2 on the top of the appliance, and an electronic cooker and a gas oven on the bottom of the appliance for combined cooking. A composite cooking device "5" having a container 4 is provided. Reference numeral 6 indicates a partition plate that partitions the stove section 2 and the composite cooking section 5.

7 indicates the top plate of the electric stove 2, 8 indicates the top that supports the electric stove 2, and the height (B) of the sink (not shown) is made to match. 9 indicates 1) 0 indicates the electric stove 2 10 is a stove case that houses the control parts for the electric outlet 2, etc. The crayon fan 12 is installed in the circulating container, and the hot air from the burner 13 for a gas oven or the hot air when used as a microwave oven is circulated through the container to uniformly heat and cook the food. 14 is for the microwave oven. Reference numeral 15 indicates an operation knob for the gas oven, and reference numeral 16 indicates an oven door. Reference numeral 17 indicates an exhaust pipe, one end of which communicates with the baking chamber 11, and the other end of which extends to near the bottom of the exhaust pipe 18 on the upper surface of the appliance. The exhaust port 18 is formed into an elongated shape that is separate from the top plate 8 of the electric stove and approximately parallel to the back surface of the appliance. 19 is an opening at the upper end of the exhaust pipe 17, and the exhaust gas is As shown in FIG. 2, the right side wall of the upper end opening 19 is bent slightly to the left so that the liquid is discharged at an angle toward the front of the device as indicated by arrow a. 20
A cooling fan cools electric control parts such as red sea bream, tron 21, or a transformer (not shown) provided on the outer wall of the baking chamber 11 by outside air flowing in from outside the appliance.

This cooling fan 20 is
It is driven in conjunction with the drive motor 22.

Reference numeral 23 designates a space in the composite cooking device 5, in which outside air is sucked in through an air supply port 24 at the lower front of the appliance, and the heat inside the space 23 is absorbed by the outside air and discharged through an exhaust port 18 on the top of the appliance. 25 indicates a combustion air intake port of the burner 13 for the gas oven.

The functions and effects of the above configuration will be explained below.

When the composite cooking device 4 at the bottom of the appliance is used as a gas oven, the cooling fan 20 located in the space 23 also rotates in conjunction with the drive of the compaction fan 12 inside the oven. As the cooling fan 20 rotates, outside air is actively taken in from the air supply port 24 to the oven gas burner 13.
A sufficient amount of combustion air is supplied to ensure more complete combustion, and the wind from the cooling fan 20 closes the magnetron 21, suppressing temperature rises in various electrical control parts, resulting in stable operation of the equipment. Further, the air which cools the electrical control parts does not cool the exhaust duct 17, but rises in the direction of the exhaust port 18, and is discharged outside the device from the exhaust port 1B. Exhaust gas is discharged from the exhaust port 18 through the upper opening 1 of the exhaust pipe 17.
9, the exhaust gas is slanted slightly toward the front of the appliance as shown by arrow a in Fig.
8 is provided separately from the top plate 7 of the electric stove 20. This increases the effective area of the electric stove 2 and brings about effects such as the conventional 30 stove can be increased to 40.

As the ventilation fan 30 shown in FIG. 4 rotates, the exhaust residue discharged from the composite cooking device comes to the exhaust port 31 via the exhaust duct 17 and is discharged to the outside from the ventilation 1ji 130. Therefore, the indoor air becomes very clean.

Effect of the invention As described above, according to the present invention, the following effects are produced.

(1) By using a cooling fan that suppresses the temperature rise of electrical control parts, cooling of the entire space is promoted, eliminating the need for a conventional dedicated fan, resulting in lower noise, energy savings, and lower costs.

(2) By separating the high-temperature exhaust gas from the wind from the cooling fan, smoke, bad odor, and toxic gas from the exhaust gas are discharged outside, improving safety.

(3) The noisy wind that was conventionally discharged from the front is now discharged from the rear, eliminating discomfort when using the device.

(4) Your kitchen will be free of stains caused by smoke and soot and will remain beautiful forever.

(5) Only the smoke-containing air (1') is exhausted outside, and other clean air can be circulated indoors, so it can be used for heating if necessary, resulting in energy savings.
